[XeTeX] Devanagari, xelatex, and \footnote

[Hueckstedt, Robert A. (rah2k)]

For my purposes, the best way of solving this problem was to use the script below, from Zdenek Wagner, from the discussion in the cikitsa website (thanks, Dominik) (note that all I did was change \dev to \dn, for compatibility, and I changed the name of the font:

\newfontfamily{\devanagarifont}[Script=Devanagari,Language=Sanskrit,Mapping=velthuis-sanskrit]{Chandas}

\DeclareRobustCommand{\dn}{%
\let~\inactivetilde
\devanagarifont}
{\catcode`\~=12 \gdef\inactivetilde{~}}

If you base it on catcode changes it will never work in the argument
of another command, not just footnotes. There is no need to switch
catcodes.

leave ~ as active always and when you want it locally to be a normal ~ do

\edef~{\string~}

so the active ~ just expands to a non-active one.
